Splitters and sockets for extension cords

Splitters and sockets for extension cords constitute a specific group of electrical equipment. They are not permanently installed inside switchboards and cabinets or on building walls, but they provide mobile access to electricity wherever it is needed, away from the power grid or electrical installation.

Splitters and sockets for extension cords - a wide market offer

When the socket of an extension cord is damaged, or it turns out that you need a tee at its end, and not a factory-fitted two-piece, instead of buying a finished product, you can replace the socket or splitter and continue to successfully use the current extension cord. The market offer now covers almost all the needs of users, guaranteeing an extremely wide range of sockets and splitters.

Available types of sockets for extension cords

Manufacturers of electrical equipment, such as Plastrol, Elgotech or Bemko, provide splitters and sockets for extension cords of various purpose and construction. You can find among them, among others:

  • straight sockets - with a pin mounted in the line of the power cord and constituting its extension, or without a pin,

  • angular sockets - with a pin mounted at right angles to the run of the power cord, or without a pin,

  • workshop sockets - made of plastic material, screwed,

  • socket sets (two, three, four and more), i.e. strips with or without a pin,

  • socket strips with a switch that allow you to disconnect the entire unit without removing the plug from the wall socket,

  • garden sockets - on a stand, with a higher degree of protection,

  • slots for drum reels.

Types of splitters

Electricity is supplied to the devices via the power grid and further via the electrical installation, which may not always be adapted to changing demand conditions. Usually, it is possible to predict the number of sockets needed in a given room or outside the building, but sometimes it is necessary to use an extension cord or a splitter that guarantees energy distribution for two, three or more sockets, from which more than one device can be supplied simultaneously.

The splitters available on the market may have the form of standard sockets with or without a protective pin, and also be equipped with a flap, while usually splitters with a flap have a protection degree of at least IP 44. Manufacturers offer splitters with the most popular E-type sockets in Poland, but also schuko or uni-schuko (suitable for schuko and type E plugs).

IP protection class

Commercially available splitters and sockets for extension cords with various degrees of protection. Standard in domestic applications is the IP 20 protection class. It does not guarantee protection against water penetration inside the housing, but it does provide protection against contact with finger conductive parts. This is a sufficient protection under normal conditions, i.e. in an operating environment characterized by the following parameters:

  • ambient temperature close to the range from -5˚C to + 40˚C,

  • maximum humidity of about 50%,

  • no exposure to direct and continuous exposure to UV radiation,

  • no dust,

  • low risk of shocks (e.g. impacts).

As a rule, these are the conditions in living quarters and public utility buildings in rooms intended for people to stay.

Other environmental conditions, such as exposure to dust, the possibility of flooding with water, the presence of harmful chemicals or the action of weather conditions, require a higher degree of IP protection. If a splitter or extension socket is to be used to increase the range of the electrical installation, e.g. in a home garage, it is worth choosing one that has a rating of at least IP 44, thus ensuring resistance to penetration of random objects with a diameter greater than 1 mm or splashed with water.
